Re: Double Sanden compressors!

blow-by is more a result of age and condition of the engine. If you get as little as you say its more than likely not going to affect anything pro or con. Now I'm jealous. I had another sanden I was going to do this with. But I seem to have misplaced it!

Re: Double Sanden compressors!

I want to do this too! A good tutorial on how to do it. BTW what kind of pliers are you using gripping that bolt head?

Re: Double Sanden compressors!

So, I'm pretty much a cheap-tool kinda guy, love me some Harbor Freight ... most of the time. I've made a few exceptions over the years - at various father's days (which coincides with my Birthday) I've had my wife get me a Craftsman mechanics tool set (all 8-point sockets) and a set of GearWrench flex combination wrenches. Those make me smile.

But those Knipex pliers I use all the time and love them. I bought both the smooth parallel jaw style and the standard channel-lock type (both in 7-inch) and just plain love them. I'd replace them again in a heartbeat.

Knipex 86 03 180:



Knipex 87 02 180:




These are the exact ones I have, and I'd pay extra for the "comfort grip" as it REALLY makes it nice when you have to clamp down hard on something.

Re: Double Sanden compressors!

Nice work! Same concept I used to run my York 210 compressor. I basically built a modified version of the Kilby Wrangler 4.0L bracket that just placed the York lower in the engine bay to clear the hood. Used to run ARB's front and rear.

York mounted beside stock A/C compressor and run on single serpentine belt.



Manifold system with pressure gauge for ARB's. One of these days I will clean this up.


Battery relocated to driverside and cold air intake installed.


Kilby 1.75g air tank mounted in cargo area.

Re: Double Sanden compressors!

I kinda want to bring this back to light and ask a question.

Why grease? Why not block off the oiler hole like it is and then run a regular motor oil in it? It wouldn't need much. I just think the grease isn't going to reach critical areas of wear whereas an oil will whip all over the place being that it is a thrash plate motor. It'll lubricate just as if it was a running AC system. Seeing as how the modification came from the minitruck realm I think I'll try oil. If it fails I'm not out very much. The JY is littered with them now.

Re: Double Sanden compressors!

The grease will liquify once it warms up. Or so the thought goes.

Re: Double Sanden compressors!

I would use a good compressor oil.
The sanden is designed to be splash oiled and most failures using grease are due to the front bearing running dry too long (the internal design has scoops and channels to aid in migrating oil into the bearing. Depending on the grease, it isn't going to liquify at all.
Then, when you replace the plug run a pipe fitting and breather on a long hose (similar to an axle breather). The Sanden service manual has the factory spec fill capacities as well. Maybe go a bit over that as it won't be as pressurized as it would in a functioning A/C system.

Re: Double Sanden compressors!

Yeah, I would probably use oil too, the bracket is an ingenious design though.

The factory setup is lubed by the oil mixed into the refrigerant charge, which is miscible (soluble in) it. That is why choosing the right refrigerant system oil is important, R12, R134a, R152a, etc refrigerants all use different oils from a few subsets, typically ester oil, PAG oil, etc.

Re: Double Sanden compressors!

What i've gathered is that it's around 2.5 oz. The breather sounds like a good idea also since the mechanical side is sealed off from the suction side by way of the plug.

Good to know! I'll be giving this a long look when it comes time to start my build.

Re: Double Sanden compressors!

Is there a long term status update? I'm about to start building the oba on my pickup.

Re: Double Sanden compressors!

I personally use an inline oiler. I -refill it with 3 N 1 oil when the oiler is dry and my compressor has been going strong for 7-8 years now.

Re: Double Sanden compressors!

I plan on doing the oiler. I'm not very confident in the grease mod. I'm thinking I'll use straight 30w.
